Such a notice grants a 46*ed0d50c3Schristosworld-wide, royalty-free license, unlimited in duration, to use that 47*ed0d50c3Schristoswork under the conditions stated herein. The ``Document'', below, 48*ed0d50c3Schristosrefers to any such manual or work. Any member of the public is a 49*ed0d50c3Schristoslicensee, and is addressed as ``you''. You accept the license if you 50*ed0d50c3Schristoscopy, modify or distribute the work in a way requiring permission 51*ed0d50c3Schristosunder copyright law. 52*ed0d50c3Schristos 53*ed0d50c3SchristosA ``Modified Version'' of the Document means any work containing the 54*ed0d50c3SchristosDocument or a portion of it, either copied verbatim, or with 55*ed0d50c3Schristosmodifications and/or translated into another language. 56*ed0d50c3Schristos 57*ed0d50c3SchristosA ``Secondary Section'' is a named appendix or a front-matter section 58*ed0d50c3Schristosof the Document that deals exclusively with the relationship of the 59*ed0d50c3Schristospublishers or authors of the Document to the Document's overall 60*ed0d50c3Schristossubject (or to related matters) and contains nothing that could fall 61*ed0d50c3Schristosdirectly within that overall subject. (Thus, if the Document is in 62*ed0d50c3Schristospart a textbook of mathematics, a Secondary Section may not explain 63*ed0d50c3Schristosany mathematics.) The relationship could be a matter of historical 64*ed0d50c3Schristosconnection with the subject or with related matters, or of legal, 65*ed0d50c3Schristoscommercial, philosophical, ethical or political position regarding 66*ed0d50c3Schristosthem. 67*ed0d50c3Schristos 68*ed0d50c3SchristosThe ``Invariant Sections'' are certain Secondary Sections whose titles 69*ed0d50c3Schristosare designated, as being those of Invariant Sections, in the notice 70*ed0d50c3Schristosthat says that the Document is released under this License. If a 71*ed0d50c3Schristossection does not fit the above definition of Secondary then it is not 72*ed0d50c3Schristosallowed to be designated as Invariant. The Document may contain zero 73*ed0d50c3SchristosInvariant Sections. If the Document does not identify any Invariant 74*ed0d50c3SchristosSections then there are none. 75*ed0d50c3Schristos 76*ed0d50c3SchristosThe ``Cover Texts'' are certain short passages of text that are listed, 77*ed0d50c3Schristosas Front-Cover Texts or Back-Cover Texts, in the notice that says that 78*ed0d50c3Schristosthe Document is released under this License. A Front-Cover Text may 79*ed0d50c3Schristosbe at most 5 words, and a Back-Cover Text may be at most 25 words. 80*ed0d50c3Schristos 81*ed0d50c3SchristosA ``Transparent'' copy of the Document means a machine-readable copy, 82*ed0d50c3Schristosrepresented in a format whose specification is available to the 83*ed0d50c3Schristosgeneral public, that is suitable for revising the document 84*ed0d50c3Schristosstraightforwardly with generic text editors or (for images composed of 85*ed0d50c3Schristospixels) generic paint programs or (for drawings) some widely available 86*ed0d50c3Schristosdrawing editor, and that is suitable for input to text formatters or 87*ed0d50c3Schristosfor automatic translation to a variety of formats suitable for input 88*ed0d50c3Schristosto text formatters. A copy made in an otherwise Transparent file 89*ed0d50c3Schristosformat whose markup, or absence of markup, has been arranged to thwart 90*ed0d50c3Schristosor discourage subsequent modification by readers is not Transparent. 91*ed0d50c3SchristosAn image format is not Transparent if used for any substantial amount 92*ed0d50c3Schristosof text. A copy that is not ``Transparent'' is called ``Opaque''. 93*ed0d50c3Schristos 94*ed0d50c3SchristosExamples of suitable formats for Transparent copies include plain 95*ed0d50c3Schristos@sc{ascii} without markup, Texinfo input format, La@TeX{} input 96*ed0d50c3Schristosformat, @acronym{SGML} or @acronym{XML} using a publicly available 97*ed0d50c3Schristos@acronym{DTD}, and standard-conforming simple @acronym{HTML}, 98*ed0d50c3SchristosPostScript or @acronym{PDF} designed for human modification. Examples 99*ed0d50c3Schristosof transparent image formats include @acronym{PNG}, @acronym{XCF} and 100*ed0d50c3Schristos@acronym{JPG}. Opaque formats include proprietary formats that can be 101*ed0d50c3Schristosread and edited only by proprietary word processors, @acronym{SGML} or 102*ed0d50c3Schristos@acronym{XML} for which the @acronym{DTD} and/or processing tools are 103*ed0d50c3Schristosnot generally available, and the machine-generated @acronym{HTML}, 104*ed0d50c3SchristosPostScript or @acronym{PDF} produced by some word processors for 105*ed0d50c3Schristosoutput purposes only. 106*ed0d50c3Schristos 107*ed0d50c3SchristosThe ``Title Page'' means, for a printed book, the title page itself, 108*ed0d50c3Schristosplus such following pages as are needed to hold, legibly, the material 109*ed0d50c3Schristosthis License requires to appear in the title page. For works in 110*ed0d50c3Schristosformats which do not have any title page as such, ``Title Page'' means 111*ed0d50c3Schristosthe text near the most prominent appearance of the work's title, 112*ed0d50c3Schristospreceding the beginning of the body of the text. 113*ed0d50c3Schristos 114*ed0d50c3SchristosThe ``publisher'' means any person or entity that distributes copies 115*ed0d50c3Schristosof the Document to the public. 116*ed0d50c3Schristos 117*ed0d50c3SchristosA section ``Entitled XYZ'' means a named subunit of the Document whose 118*ed0d50c3Schristostitle either is precisely XYZ or contains XYZ in parentheses following 119*ed0d50c3Schristostext that translates XYZ in another language. (Here XYZ stands for a 120*ed0d50c3Schristosspecific section name mentioned below, such as ``Acknowledgements'', 121*ed0d50c3Schristos``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' 122*ed0d50c3Schristosof such a section when you modify the Document means that it remains a 123*ed0d50c3Schristossection ``Entitled XYZ'' according to this definition. 124*ed0d50c3Schristos 125*ed0d50c3SchristosThe Document may include Warranty Disclaimers next to the notice which 126*ed0d50c3Schristosstates that this License applies to the Document. These Warranty 127*ed0d50c3SchristosDisclaimers are considered to be included by reference in this 128*ed0d50c3SchristosLicense, but only as regards disclaiming warranties: any other 129*ed0d50c3Schristosimplication that these Warranty Disclaimers may have is void and has 130*ed0d50c3Schristosno effect on the meaning of this License. 131*ed0d50c3Schristos 132*ed0d50c3Schristos@item 133*ed0d50c3SchristosVERBATIM COPYING 134*ed0d50c3Schristos 135*ed0d50c3SchristosYou may copy and distribute the Document in any medium, either 136*ed0d50c3Schristoscommercially or noncommercially, provided that this License, the 137*ed0d50c3Schristoscopyright notices, and the license notice saying this License applies 138*ed0d50c3Schristosto the Document are reproduced in all copies, and that you add no other 139*ed0d50c3Schristosconditions whatsoever to those of this License.
